C HAPTER 2 I NSTALLATION
Option DIP Switch Settings
Switch 1: Latch Enable/Disable
Default setting = Open: Enable.
Description: An intercom key can always be turned on for momentary conversation by pressing
and holding the key during the conversation. There is also an electronic latching feature that lets
you tap intercom keys to turn them on or off. This permits convenient hands-free conversation.
However it can also result in a talk circuit being left on unintentionally. For example: A key that
talks to a public address system could be accidentally left on. Or an IFB key (a type of key
assignment that is often used by a director or producer to give instructions to a listener, such as a
news anchor during a television broadcast) could accidentally be left on, causing confusion for
the IFB listener. To prevent such accidents, the latching feature can be turned off.
Note DIP switch 1 disables latching for the entire keypanel. If you just need to disable latching for
selected keys, leave DIP switch 1 in the "Open" position. Then, disable latching for the desired
keys using the "D" check boxes in the Keypanels / Ports setup screen of ADAMedit.
Switch 2: Key Gain Enable / Disable
Default setting = Open: Enable.
Description: Enables or disables the Key Gain item in the Key Assign menu.
Switch 3: Screen Saver Enable / Disable
Default setting = Open: Enable.
With Screen Saver enabled, the KP-832 will shut off the display and enter a low-power state after
a few minutes of inactivity. The display reactivates instantaneously on incoming call or when the
keypanel operator actuates any control. As with all fluorescent and back-lit LCD displays, some
dimming will occur after many years of operation. Using the screen saver helps maximize the
display life.

2-2 KP-832 User Manual
Switch 4: Call Flash Timeout
Default setting = Open: 15 Second Flash.
Description: Whenever there is an incoming call and there is a talk key assigned to the caller, the
talk LED next to that key will flash. The flash can be set for 15 second timeout, or until the
caller's talk key is released.
Note Future versions of ADAMedit and ZEUSedit will be able to override the Call Flash Timeout
setting.
Switch 5: Footswitch Enable / Disable*
Default = Open: Disabled.
Description: The optional Connector Module has a footswitch (GRP CALL) input. If the
footswitch is enabled (DIP switch 5 set to the "Closed" position), then keys that are latched on
will not activate until the footswitch is closed. Latched keys are indicated by winking green talk
LEDs (on time less than off time), and when the footswitch is activated, the LEDs provide the
normal talk-on indication.
Notes 1If the talk key is held down in Footswitch mode the channel will be activated until the user
releases the key. The use of this function does not require the footswitch to be used.
2If DIP switch 1 is set to the “Closed” position, nothing will latch.
3Individual keys can be set to non-latching via ADAM Edit. If this is done, the footswitch has
no effect on the keys that have been set to non-latching. Please see ADAM Edit help for more
information.
Switch 6: Network Mode Selection
Default Setting: Open (Mode 1)
Description: In the Mode 1 setting, the keypanel functions operate as called out in the main
portion of this manual. If the switch is closed (Mode 2), then the functions operate as outlined in
this manual with slight modifications. Any function that is affected by Mode 2 operation will
have an asterisk (*) by it. The changes/modifications to the functionality is called out in the
section titled “Mode 2 Operation”
Switch 7: Test/Debug
Default Setting: Open.
Switch 8: Test/Debug
Default Setting: Open.
Address Switch Setting
General Information
In Zeus, ADAM CS, and ADAM Intercom Systems, intercom ports are arranged in groups of
eight. All ports in a group share a common data port. Each KP-832 keypanel is uniquely identified
on the data port by the setting of its Address switch. The method of determining the proper
Address switch setting varies for each intercom system. Use the method for your intercom system
as described below. Then set the white pointer on the Address switch to point to the correct
setting.

Address Setting for Zeus
Intercom port connectors on the Zeus back panel are arranged in three groups of eight intercom
ports. For each group, intercom port connectors are labeled ID 1, ID 2, etc. When you connect a
KP-832 keypanel to Zeus, set the Address switch to match the corresponding ID number on the
Zeus back panel. Note that address switch settings 0, and 9 through F are not used.
Address Setting for ADAM CS
Each Audio I/O card contains 1 group of 8 intercom ports. However, the method of breaking out
the groups depends on the type of connectors on the back panel.
ADAM CS with RJ12 or DB-9 back panel:
The intercom port connectors are arranged in groups of 8. The first connector at the left for each
group is Address 1, the next is Address 2, and so forth.
Note Address switch settings 0, and 9 through F are not used.

Figure 2.1. To use the table, locate the intercom port number to which the KP-832 will be
connected. Then, read across to the "Address" column to find the Address number. Set the KP-
832 Address switch to this number. Note: settings 0, and 9 through F are not used.
